For example: To minimise error and improve clinical and research practices, standardisation and documentation of the following is critical: Reliability is the study of error or score variance over two or more testing occasions [3], it estimates the extent to which the change in measured score is due to a change in true score. For all participants that are not accustomed to exercise, it would be wise to conduct a PARQ - Physical Readiness Questionnaire. CALCULATING THE SEM. 19(10): p. 811-827. between testers. All worksheets are included and ready to print within the bundle. In this page we look at the purpose and benefits of fitness testing for your clients, and the unfortunate consequences of poorly performed testing. For example, an assessor trained in skin-fold measurements will produce the same result, when the same area is re-tested shortly after. Intraclass Correlation Coefficient (ICC) is considered as the most relevant indicator of relative reliability [2]. Finally, it does not represent agreement between testing occasions [19].

In other words, when the data appears in a bell-shaped curve around the centre of the graph as in Figure 2 it suggests that 95% of the data revolves around the mean by 2 Standard Deviations. The dimension of the test values (calibration or scaling across ergometers and analysers) needs to be accounted for when comparing the same population across different tests [5], as differences in scales will affect SEM size. Fitness testing can take a long time, especially when working with large groups of people e.g. To ensure quality for our reviews, only customers who have purchased this resource can review it. sample characteristics: Regional vs. Olympic Athletes or testing procedures: timing gate height).

For a more practical outlook, practitioners can base their judgement of appropriateness on confidence intervals (CI) calculated as shown below: For example, if isokinetic quadriceps strength measured is 140 Nm and the specific test SEM is 15 Nm, statistical theory tells us that we can be 68% confident that true score is between: (140 15 = 125 and 140 + 15 = 155).

As previously mentioned, a change in the group mean across testing occasions suggests a systematic error which, depending on its size, maybe due to design issues: When sample size increases, the random error component will tend to cancel out across participants (it is random, so eventually it cancels out).
